Fellow Ubuntu users! I recently dual-booted Windows 7 and Ubuntu 11.10, and I am in a bit of a fix. When I want to connect to the internet with Ubuntu, Network Manager is showing that my device is not ready to use (exactlty device not ready). It works fine on Windows, however, since I'm using the same computer to type this as the one that is having the problem right now.

I also forgot to mention that Network Manager can tell me whether the switch for the wireless is on/off, but it does not do anything besides say "your hardware is turned off by a switch", if off, and the "device not ready" if on. I also tried rebooting. It didn't work.
